1.Why scaling? Deposited on the teeth of tartar, plaque, plaque and stains, very unattractive, more likely to cause periodontal disease and bad breath, but daily brushing is not brushed off, which requires the dentist to use a special instrument to remove it clean, known as scaling. 2.What is tartar? Plaque and saliva in the calcium and phosphorus ions combined with calcium conjugation into tartar. It is like the scale at the bottom of a kettle after boiling water. No matter how well you brush your teeth, tartar will always form over time. However, depending on the individual, some people will have more tartar while others will have less. Those with well aligned teeth are relatively easy to brush less. The teeth are not aligned will be relatively more. 3.What kind of equipment is used for teeth cleaning? There are ultrasonic scaler, sandblast scaler and hand scaler. If there is only tartar, ultrasonic scaler can be used. If there is less tartar and more stains, sandblasting is used. If there is a lot of tartar and stains, a combination of ultrasonic and sandblasting is recommended. For subgingival tartar, poor periodontal condition, advocate a week after the ultrasonic scaling manual scraping. This effect will be better. 4, scaling hurt teeth? Why do so many people say scaling is not good? Dental scaling damage to the teeth is quite slight. Relative to the protection of dental health, that a little damage is negligible, as we do not need to worry about washing the bowl will wash the bowl thin. However, the method of cleaning your teeth is important. Choosing a doctor and a cleaning assistant is important. For ultrasonic scaling, the key is to control the angle between the ultrasonic head and the surface of the teeth, and not to vibrate at the same point for too long, in addition to controlling the power of the scaling machine. The operator’s gestures should be gentle. If the action is rough not to damage the teeth is false. 5, after washing once need to wash again? There is no once-and-for-all thing in this world. Because the teeth are used every day, will be dirty again. 6.How often is it appropriate to clean the teeth? Half a year to a year or so. Depending on the specific conditions of your mouth and the recommendations of the dentist. 7.How long does it take to clean my teeth? 40 minutes to an hour or so. Depends on your oral cavity. Too short would be wrong. 8.Why do some people’s teeth become loose after cleaning? If your teeth periodontal condition is good, less calculus, the correct cleaning method will never loose teeth. For those who have bad periodontal condition and a lot of tartar before, it is possible to have this “loose” phenomenon – it is actually a normal phenomenon. We compare the teeth to a big tree, the nutrition of the tree depends on the soil next to it to supply, if there is a big tree it is next to the stone, then it is very solid, but because of the lack of nutrients, it will slowly die, so we need to remove the stone, to give it to cultivate the soil, although just take away the stone to replace the soil when the tree will be a little loosened, and then the soil solid, it will be fine. The stability and nutritional source of the tooth depends on the gums and alveolar bone next to it. If there is tartar next to the teeth, although the teeth are stable, they will die later because there is no nutrition. It’s a little loose at the time though. It’s good for the long term.
